PP Nonwoven Needlepunch Geotextiles

We hold specialization in the domain of manufacturing and exporting the variety of PP Nonwoven Needlepunch Geotextiles. Mainly used with the geomembranes, these are highly deigned with protective cushions. Highly durable in nature, the preferred products are made by using the best grade polypropylene fibers tangled together by applying the needle punching approach. We provide the range of PP Nonwoven Needlepunch Geotextiles to our respected clients™ at market leading prices.

Needle-punched non-woven Geotextiles are made from polypropylene fibres that are tangled together by a needle-punching process. The fibres may be made in continuous or short lengths (the short length fibres are called staple fibres) and achieve their strength by interlocking. Needle-punched non-woven Geotextiles have excellent water flow rates and are used for filtration of soil fines for drainage applications including trench drains, as a wrapping for perforated pipe, for erosion protection, and combined with three-dimensional structures to create prefabricated drains. Needle-punched non-woven primary functions: filtration; separation; protection; drainage. Secondary functions: reinforcement.

Geotextile Functions

Separation function: Separation of two layers of soil with different soil physical properties, such as road gravel from soft sub-base materials.

Filtration function: Retaining fine particles when water passes from a fine-grained to a coarse grained layer, such as when water flows from a sandy soil into a Geotextile wrapped gravel drain.

Drainage function: To drain liquid or gas in the plane of the fabric which results in draining or venting of the soil, such as a gas vent layer in a landfill cap.

Reinforcement function: Improving the load bearing capacity of a soil structure, such as a high strength Geotextiles to reinforce a retaining wall.

Protection function: Mechanical protection of geomembranes against perforation and abrasion, such as a liner protective layer when only gravel fills are available.
